No, I think that it's great that you mentioned that. I said I was guessing about how long the T reeds have been around. This is how we all learn. The main thing I've learned so far is that calling the reeds with "T" tupelo is a southwest Louisiana phenomenon. Also that there are two types of Hohner reeds in meodeons/accordions. These two types have different tonal qualities. One can distinguish between them by looking at the metal composition. And now I've just learned that there are some of the earlier models of blue steel that are stamped with a "T". And I've also learned that the "T" probably refers to "Trossingen."

I love learning all this stuff!
